Battery pack

Abstract:

In a battery pack, a cover is fixed to a case by a special component. A first service plug includes a special tool detaching the special component. Part of the first service plug or part of a first lid closing it and part of a second service plug or part of an annular component between a second housing part and a second lid closing it are superimposed together via a superimposed part. In the superimposed part, part of the first service plug or part of the first lid is positioned on a deeper side in a direction where the first service plug and the first lid are detached. Accordingly, the first service plug cannot be detached unless the second service plug is detached, and unless both the first and second service plugs are detached, the cover cannot be detached from the case using the special tool, thus ensuring safety.
